What does a solid white line indicate?

A solid white line serves as a clear visual signal for drivers to indicate that lane changes should be avoided. This means that when you see a solid white line, it signifies a restriction on crossing that line, often found at lane boundaries or on the edge of the road. These markings enhance safety by clearly demarcating lanes and guiding traffic flow, as well as indicating areas where stopping is not allowed, like on certain highways or busy streets. The intent behind these markings is to minimize confusion and prevent collisions by encouraging drivers to remain within their designated lanes. Understanding this can help drivers make safer decisions on the road.
